One Israeli Border Guard told me "Our systems could see if a Bird was flying-in; yet authorities would have us believe they couldn't see dozens of Palestinians on motorized para-gliders in the air?  It's simply not possible.  They let this happen on purpose."

Another Israeli told me "MOSSAD knows when these people, HAMAS, take a dump in the bathroom, yet we're supposed to believe MOSSAD had no idea this gigantic operation was being planned?"

Israel has the best intelligence on its neighbors of any nation on earth. Israel has lots of "assets" embedded in these various "terrorist" organizations, as well as SIGINT (including U.S. satellite data) which allows Israel to always have a finger on the pulse of these organizations.

There is no way in hell that a coordinated, major attack involving about 1,000 Hamas fighters, sea-based/ land-based/ aerial attacks could have been planned, coordinated, and executed without Israeli intelligence getting wind of it. 0% chance.
